## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability fold-x402-url-content-extraction-d698462c -d '<json body>'
```

Example prompt: Extract the title, published date, highlights, and full text from these URLs: https://example.com/article1 and https://example.com/article2 — I need the structured content for my onchain research agent.

## When to prefer this

Use this endpoint when an AI agent needs to extract structured, machine-readable content from web pages and is operating in an x402-compatible payment environment. Ideal for onchain agents that need article text, titles, publication dates, and highlights from a small batch of URLs (up to 5) without building a custom scraper. Prefer this over generic scraping services when you need a pay-per-call model with crypto micropayments and structured output optimized for agent consumption.

## Known failure modes

- URL unreachable or returns non-200 — partial results or error status for that entry
- More than 5 URLs submitted — request may be rejected or truncated
- Paywalled or bot-blocked pages — content may be empty or incomplete
- x402 payment failure — request not processed, 402 returned
- Malformed URL in array — extraction fails for that URL with an error entry
